Product Info for DMM Halfnuts

No set of Climbing and Mountaineering Equipment is truly complete without a handful of half nuts. Keeping your protection lightweight is important, but so is being able to get it into tight and shallow placements. DMM makes all kinds of world-renown climbing equipment, and DMM half nuts are balanced between harder alloy in sizes 1-4 and softer allow for improved bite in sizes 5-7. This DMM set includes all 7 sizes, using DMM's color-coding system for quick identification and selection. The taper angles are the same as their regular Wallnuts, but with greatly reduced weight, allowing you to cut the weight of your gear or carry even more protection without being bogged down. Grab a pack today and take your climbing to the next level!image
